Furthermore, we've shown a prototype of our new SecuFirm2™ mounting system for Intel's new socket 1366 (Nehalem/Bloomfield): The new mounting kit is designed for maximum security and convenience and will be backwards compatible with all Noctua CPU coolers since 2005. All users of Noctua CPU coolers will be able to obtain the kit either for free or at a very low service charge (to be determined) upon presenting a proof of purchase (scan or photo of the invoice).
